Carbon Content Classification	Quality & Application Classification	Hot-Rolled State	Cold-Rolled State
Low-Carbon Steel (C ≤ 0.25%) Characteristics: Excellent plasticity, toughness, and weldability	Ordinary Structural/Commercial Grade (Primarily guarantees mechanical properties, lowest cost)	• ASTM A36 • SS400 (JIS) • S235JR (EN) • Q235A/B (GB)	• DC01 (EN) •SPCC (GB/JIS) • CR2/CR3 (ASTM)





	Quality Structural/Drawing Grade (Strict control of both composition & properties, good formability)	• A572 Gr.50 (ASTM) • SM490A (JIS) • S355JR (EN) • Q355B/C/D (GB)	• DC03, DC04 (EN) • SPCD (GB/JIS) • DQ, DDSK (ASTM)





	Advanced Forming/Deep Drawing Grade (IF Steel) (Ultra-deep drawing, non-aging)	Rarely used directly as sheet. Typically serves as the hot-rolled coil feedstock for cold-rolled deep-drawing steels.	• DC05, DC06 (EN) • SPCE, SPCF (JIS/GB) • EDDQ/S-EDDQ (Generic)




	High-Strength Low-Alloy (HSLA) / Advanced High-Strength Steel (AHSS) (High strength, balances formability & weldability)	• A572 Gr.60/65 (ASTM) • S420MC/S460MC (EN) • Q390/Q420/Q460 (GB)	• HC340/590DP (GB, Dual Phase steel) • DP600, TRIP800 (Generic) • HCT600X (EN)





Medium-Carbon Steel (0.25% < C ≤ 0.60%) Characteristics: Good strength-toughness combination achievable via heat treatment	Machinery Manufacturing Steel (Used for core load-bearing parts after quenching & tempering)	• 1045 (SAE) • S45C (JIS, hot-rolled material) • 45# (GB, hot-rolled plate/flat bar)	• 1045 (SAE, cold-rolled strip) • S45C (JIS, cold-rolled precision material) • 45# (GB, cold-rolled precision stock)





High-Carbon Steel (C > 0.60%) Characteristics: High hardness, high wear resistance, high brittleness	Tool & Special Purpose Steel (Belongs to special steel category)	• 65Mn (GB, spring steel flat bar) • 1095 (SAE) • T8, T10 (GB, Tool Steel)	Very rare. May exist as cold-rolled strip or thin sheet for making high-precision spring strips, blades, or special wear-resistant shims.
